This was a mixed study (quantitative and qualitative). Students’ grades, district assessments, state assessments, and teacher surveys were analyzed. The results showed that students improved their math and English Language Arts (ELA) district assessment scores when compared from …

Educational Neuroscience, Educational Psychology, And Classroom Pedagogy As A System, Alexander Vaninsky

Publications and Research

This paper introduces a view of educational process as a 3-layer system comprising human brain, personality psychology, and classroom pedagogy. It aims to present a classroom as a place where educational neuroscience and educational psychology meet to result in effective pedagogy. The paper demonstrates the advantages of such approach for mathematics education. Among them are understanding of mathematical anxiety as a defensive reaction of the brain on operating memory overflow, finding gifted and talented students objectively, assertion of possible limitations on the educational goals given unfavorable conditions, restricted time of information perception, limited liability of teachers and instructors for the …

The Effects Of A Discrete Covariatonal Approach To Functions Through Computer Programming On Students' Understanding Of Rate Of Change, Michael Wayne Strange

Open Access Theses & Dissertations

Having a broad understanding of functions is paramount to student success in higher math classes, however most students fail to fully develop this concept during their high school years. While the concept of function is multifaceted and a full understanding requires a broad knowledge base, understanding rate of change can be considered a fundamental component of the concept. Unfortunately, even AP Calculus students have difficulty with rate of change (Teuscher & Reys, 2012). The problem may stem from the approach taken in most curricula that focus on the correspondence view of functions rather than the covariational perspective as advocated by …
